FAN7393A
Half-Bridge Gate Drive IC
Features
Description
„ Floating Channel for Bootstrap Operation to +600V
The FAN7393A is a half-bridge gate-drive IC with shutdown and programmable dead-time control functions
that can drive high-speed MOSFETs and Isolated Gate
Bridge Transistors (IGBTs) operating up to +600V. It has
a buffered output stage with all NMOS transistors
designed for high-pulse-current driving capability and
minimum cross-conduction.
„ Typically 2.5A/2.5A Sourcing/Sinking Current Driving
Capability
„ Extended Allowable Negative VS Swing to -9.8V for
Signal Propagation at VBS=15V
„ High-Side Output in Phase of IN Input Signal
„ 3.3V and 5V Input Logic Compatible
„ Matched Propagation Delay for Both Channels
„ Built-in Shutdown Function
„ Built-in UVLO Functions for Both Channels
„ Built-in Common-Mode dv/dt Noise Cancelling Circuit
„ Internal 400ns Minimum Dead Time at RDT=0Ω
„ Programmable Turn-On Delay Control
Fairchild’s high-voltage process and common-mode
noise canceling techniques provide stable operation of
the high-side driver under high dv/dt noise circumstances. An advanced level-shift circuit offers high-side
gate driver operation up to VS=-9.8V (typical) for
VBS=15V.
(Dead-Time)
The UVLO circuit prevents malfunction when VDD and
VBS are lower than the specified threshold voltage.
Applications
The high-current and low-output voltage drop feature
makes this device suitable for diverse half- and fullbridge inverters; motor drive inverters, switching mode
power supplies, induction heating, and high-power DCDC converter applications.

Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The
absolute maximum ratings are stress ratings only. TA=25°C unless otherwise specified.

Notes:
1. This IC contains a shunt regulator on VBS. This supply pin should not be driven by a low-impedance voltage
source greater than VSHUNT specified in the Electrical Characteristics section.
2. Mounted on 76.2 x 114.3 x 1.6mm PCB (FR-4 glass epoxy material).
3. Refer to the following standards:
JESD51-2: Integral circuits thermal test method environmental conditions - natural convection, and
JESD51-3: Low effective thermal conductivity test board for leaded surface mount packages.
4. Do not exceed maximum PD under any circumstances.
Recommended Operating Conditions
The Recommended Operating Conditions table defines the conditions for actual device operation. Recommended
operating conditions are specified to ensure optimal performance to the datasheet specifications. Fairchild does not
recommend exceeding them or designing to absolute maximum ratings.
